A very good way is similar to gambling. You buy them, and then sell them when the price has gone up. I managed to make 1.2BTC that way. However, be careful when you buy/sell as it will depend in the price. Always choose the right time to do so.
Gambling is not the safest way to make some money. I would recommend high volume PoS coins, even if the price goes down a bit, one still can reach ROI, just have to wait a bit longer.
BTW, I like your nick.
